Jack Petroske was not originally selected to play on the 1956 Olympic team, failing to survive the final cut. However an injury to Frank O’Grady opened up a spot on the team and Petroske was able to play at Cortina. Petroske was a college junior at the University of Minnesota at the time. He played hockey all four years at Minnesota, and also represented the U.S. at the 1958 World Championships after graduation in 1957. After marriage, Petroske settled in his hometown of Hibbing, Minnesota. He started Range Industrial Supply and ran that company successfully for over 30 years before retiring.
